Application nlcd January 21, H527, Serial No. 162,546, and in Germany lay 12, 192'6.

Knitting machines, particularl of the straight-bar type, are provided wit a' transfer comb wh'ereby the pressed-off portions of a stocking leg are transferred to the needle vbar for the knitting of the foot. In known machines the comb is carried by means of arms on a rock shaft which, in order to leave the essential working parts of the machine unobscured, is arranged below the level -of lo the sinkers. With the rock shaft in this position, the transfer comb follows a circular path which traverses the needle path at a considerable angle, and the vtransfer is therefore unreliable and gives rise to throw-outs l5 and to waste of time.

The object of the present invention is to .provide means forrectif ing the position of 1 -the rock shaft without obstruct-ing the view, A and the invention consists in arranging the shaft so that it can'be raised to the level of the sinkers for operation and lowered when 'notinusa A A Preferabl theshaft is for this purpose mounted in rackets which are pivotally adjlstfzble for varying the position of the rock The invention is illustrated in the accom panying drawing by a sectional view of lthe arrangement.

The transfer comb c 1s held in forks b at the up-turncd ends of arms a which are secured to the rock shaft il. According-to the invention,I the latter is mounted in brackets z' secured to a shaft k, the latter being arf ranged ,over the table e'in about the same position as the rock shaftin the old arrangement.v Normally the arms and brackets are turned over into the position shown by dotted lines in the figure and will therefore be out 40. of the way. When the comb lis to be used; the elements are" turned into the position shown by full lines, this position being'raetermined by the' abutment against the table e of nose pieces m on the brackets. In this s position, the rock shaft will be on a level 'f substantially coinciding with that of the ina reliable manner.

sinkers fn, and the circular path g of the transfer points of the comb will be subst-an` 'tially parallel and coincident with the needles la. so that the transfer will be effected 1.. In a knittin machine having a needle' b ar and a trans er combL arranged respectively below and above' the sinkers, arms 55 carrying ,said transfer comb, a rock shaft holdin said arms and means forsupportlin sa1d rock shaft so that it can be raised su stantially to thelevel ofl the sinkers for operation and lowered when not in use, Sub` 6'0 stantially as and for the-pur 'ose set forth.

2. In a knitting machlne aving a needle bar and a transfer comb'arranged respectively below and above the sinkers, arms car ing said transfer comb, a rock shaft Y y' hol ing said arms, and means for supporting said rock shaft so that it can be swung parallelly with itself into and out of operative position, the shaft being substantially on a level with the sinkers in the operative position, substantially as and for the purpose set forth. l

3. In a knittin machine having a needle bar and a trans er comb 4arranged respectively .below and above the sinkers, arms carrying said transfer comb, a rock shaft holding said arms, and (pivotall adjustable brackets supporting sai rock s aft sothat it-can be swung parallelly with itself int'o and out of operatlve position, the shaft being. substantially on a level with the sinkers in the operative position, substantially as and for the purpose set forth.

1 i 4. The structure claimed in claim 3, nosepieces connectedv to the brackets, and an abutment for said' nose-piecesv determining the operative position of the rock shaft.
